Natural Pearl/ Nacre - The Jyotish Gemstone of the Serene Moon

According to Jataka Parijaata the jyotish gemstone, gem of the Moon is the natural pearl Pearl. Like the Moon which exudes cool pleasing rays, the Natural Pearl too ensures peace of mind and contentment. Pearls are treasures from the Earth’s streams, rivers, lakes, seas, and oceans, and they have always embodied the mystery, power, and life-like sustaining nature of water.

The Moon is feminine, imaginative, receptive, sensitive, intuitive and subject to change. It acts as a large crystalline transformer, converting solar energy which reflects to the planet Earth. The Moon rules over our psyche, which is represented by the deer on which he rides. In one hand he is holding the disc (charka) of Vishnu to remove obstacles, and in another hand a conch (Symbol of primordial sound) whose sound leads to liberation from the cycle of birth and rebirth. In his third hand he holds a lotus of purity and in his fourth hand the reins of the deer.

Moon is the presiding deity of the element water, and rules over the tides of the sea. The sphere of the Moon is the reservoir of rainwater and thus Moon is the ruler of plants and vegetable kingdom. Moon represents the mother or female principle, the energy that creates and preserves.

Formation of a Natural Pearl

Formation of a pearl inside an oyster is thought to occur because of foreign material inside the body of the oyster. To save itself from the undesired material the mollusk coats the object with layers of nacre. It takes many years for a mollusk to produce a pearl of substantial size. The process through which the pearls are formed inside the body of the mollusk is very delicate, and a little disturbance at any stage of development of a pearl can influence its shape and luster. The finest pearl is that which has no foreign matter in its core. There is a common belief that when Swati Nakshatra rain comes to earth it produces pearl in pearl oysters. The mollusk is then said to open its mouth to receive the first raindrops. The pearls thus produced by the raindrops of Swati Nakshatra are the finest and have no foreign matter in them.
